I figured I'd share my awesome find just in case this isn't already common knowledge. . . even if it is, I still think it's awesome.

"The Mat" by Sleep Innovations is the best dog crate mat I've ever seen. I found one at costco for less than $10 and had to try it. Mine looks a little bit different than theirs, but it's the 24x36" and fits perfectly in the crate. It's soft, cushy memory foam with a fuzzy microfiber top that you can probably wipe pet hair off of. The bottom has a rubber backing so that it grips the crate and won't slide around, and it's so thick Middie can't dig it up like he does with blankets.

It was cheaper than a typical crate mat because it's designed for the bathroom, is machine-washable, and way more cushiony - and is just the right size for a medium-size dog crate!

I'm thinking I'll get some pvc, and elbows, and make a 'frame' that fits into the bottom of the crates, then take that to a lady who does sewing and get her to make a bed/cover that goes over it. I'd like to have the crates IN the indoor area of their 'room' but at the moment I have to keep the crate doors shut or they'll drag their beds outside into the snow/mud. But the foam ones sound good for travel.... hm.....
